The version store cannot grow because it is receiving out-of-memory errors from the operating system. Updates to the database are rejected until long-running transactions are rolled back or deleted. Contact support if problem persists.

This Warning event indicates that the version store cannot grow because it is receiving out-of-memory errors from the operating system. The version store is where the Exchange Information Store service keeps records of transactions that are not yet finished. It is likely that a long-running transaction is preventing cleanup of the version store and causing it to increase in size. Updates to the database are rejected until long-running transactions are rolled back or deleted. When the version store is full, any updates to the database are rejected until the long-running transaction is completely committed or rolled back. This causes a service interruption for users.

If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
